This upgrade is completely backward-compatible and recommended for all users on versions below 12.0.9
Vulnerable code could allow a bad actor to trigger a denial of service attack via the /${locale}/_next/ route for anyone running a Next.js app at version >= 12.0.0, and using built-in i18n routing functionality.
How to Upgrade
We have released patch versions for both the stable and canary channels of Next.js.
To upgrade run npm install next@latest --save
Impact
Affected: All of the following must be true to be affected by this CVE
Next.js versions between v12.0.0 and v12.0.9
Using next start or a custom server
Using the built-in i18n support
Not affected:
Deployments on Vercel (vercel.com) are not affected along with similar environments where invalid requests are filtered before reaching Next.js.
We recommend everyone to upgrade regardless of whether you can reproduce the issue or not.
How to Assess Impact
If your server has seen requests to any route under the prefix /${locale}/_next/ that have triggered a heap overflow error, this was caused by the patched issue.
What is Being Done
As Next.js has grown in popularity and usage by enterprises, it has received the attention of security researchers and auditors. We are thankful to our users for their investigation and responsible disclosure of the original bug.
We've landed a patch that ensures this is handled properly so the requested route no longer crashes and triggers a heap overflow.
